Determining Method of Article Transfer Place, Determining Method of Landing Place, Article Transfer System, and Information Processing Device

2. The control method according to claim 1, wherein a search is made for a space where the unmanned ground vehicle can stop for a predetermined time or more with reference to the candidate ground location, and the searched space or a point in the searched space is determined as the article transfer place or the landing place.

3. The control method according to claim 1, wherein a search is made for a space in which ground and sky surroundings are free of obstacles with reference to the candidate ground location, and the searched space or a point in the searched space is determined as the article transfer place or the landing place.

4. The control method according to claim 1, wherein the article transfer place or the landing place is determined based at least in part on the information obtained from the second sensing while the unmanned ground vehicle is moving according to the movement control.

5. The control method according to claim 1, wherein the article transfer place or the landing place is determined based at least in part on information obtained from third sensing performed by a sensor installed on the ground.

6. The control method according to claim 1, wherein the article transfer place or the landing place is determined based at least in part on a past transfer history or a past landing history.

7. The control method according to claim 1, wherein a search is made for a space where the unmanned ground vehicle can stop fora predetermined time or more, and the searched space or a point in the searched space is selected as the candidate ground location.

8. The control method according to claim 1, wherein a search is made fora space in which ground and sky surroundings are free of obstacles, and the searched space or a point in the searched space is selected as the candidate ground location.

9. The control method according to claim 1, wherein the candidate ground location is selected based at least in part on information obtained from third sensing performed by a sensor installed on the ground.

10. The control method according to claim 1, wherein the candidate ground location is determined based at least in part on a past transfer history or a past landing history.

12. The control method according to claim 11, wherein the predetermined criterion is a proximity to a delivery destination of the article.

13. The control method according to claim 11, wherein the predetermined criterion is a proximity to a current position of the unmanned ground vehicle.

14. The control method according to claim 11, wherein the predetermined criterion is a density of surrounding candidate ground locations.

15. The control method according to claim 1, further comprising causing the unmanned aerial vehicle to fly to the determined article transfer place or landing place.

16. The control method according to claim 1, further comprising causing the unmanned aerial vehicle and the unmanned ground vehicle to perform an article transfer at the determined article transfer place or landing place.

17. The control method according to claim 1, further comprising outputting an alarm in a case where an approach of a moving object to the determined article transfer place or landing place is detected.
